Cross-selling involves offering a customer a complementary product, accessory, or service related to their main purchase. This technique aims to enhance the shopping experience by suggesting related items, such as shoe polish with a pair of shoes or a tie with a shirt. It is generally offered proactively by a salesperson, but can also be automated on e-commerce platforms or in large retail stores without direct intervention.

Cross-selling, also known as upselling, involves offering a complementary product, either during or after a purchase, to increase sales by raising the total transaction amount. Originally, this technique was primarily used in physical stores, where a salesperson would suggest additional products. A classic example of cross-selling was selling a tin of shoe polish with the purchase of shoes, or suggesting a shirt or tie with a suit.

In the retail sector, cross-selling can take various forms. It can also be fully automated on an e-commerce platform, thus offering a personalized customer experience. In French, the term cross-selling is translated as "vente complémentaire" or "vente croisée," and it differs from upselling.

A humorous and illustrative example of an extreme approach to cross-selling in a store involves a salesperson or point-of-sale advisor.
